On Sat., April 17, 2010, the Hyperion instrument on-board NASAs Earth Observing-1 (EO-1) spacecraft obtained this pair of images of the continuing eruption of Icelands Eyjafjallajökull volcano. In the left-hand image, created from visible wavelengths, new black ash deposits are visible on the ground, as well as nearby brilliant unsullied ice and snow and the volcanos brown, billowing plume. The plumes dark colour reflects its large ash content. These fine particles of pulverized rock are carried high into the atmosphere, where they create a hazard for aviation and are carried long distances by the prevailing winds. In contrast, the false-colour, infrared image at the right reveals the intense thermal emissions (at least 60 megawatts, or 60 million watts) emanating from the vent at the base of the massive plume. This thermal emission, equivalent to the energy consumption of 60,000 homes, represents only a small proportion of the total energy being released by the volcano as its molt
